garmin coach not synced between devices

although my question looks similar to other questions regarding the garmin coach not synced on fenix although everything is on the mobile app I've another bit of concern. 
my edge 1040 is howing something a bit different than the garmin coach app . 

to summarize : 

fenix 6 doesn't show the garmin coach planning
the mobile app says to rest 
the edge 1040 says I should train 

How to have all the devices synced ? that's the main reason I have a fenix and egde
